: Modifying Nivomat shocks for lowering springs, necessary?

09-27-11, 05:36 PM
I noticed recently that my car has Eibach lowering springs in the rear. I ran into this,
Modifying the FE4 (or FG2) Nivomat shocks for lowering springs (http://www.cadillacfaq.com/faq/answers/lowercts/index.html) and got to thinking...

Did the previous owner modify the shocks to accommodate the lowering springs?

I am inclined to doubt that they did, but is there an easy way for me to verify this?

Furthermore, is this necessary if you put lowering springs on?

Ok, so after a bit of research it is looking like if I pull back the trunk carpet I can see the top of the shocks. And, if I am reading into this correctly I will be able to tell if the shock is sitting on spacers. Does anyone have any experience with this. What am I looking for exactly?

Does that look like a spacer?

Difficult to tell with that small of a pic... Looks like an OEM shock mount though, which means no spacer.

Yup, looks OEM to me too.
You can answer your own question about the need for spacers if you simply measure from your floor to the middle of your fender lip (through the middle of the wheel) after the car has been sitting overnight. Then go do some driving around. As soon as you get back home and park the car, measure again. There should be a significant difference if your shocks are working correctly and there aren't any spacers installed.
